 This makes me think the find_xcode_sysroot.py script is expecting to be
 run with python 2 (which is Apple's system python version) but you might
 have used `port select` to select a version of python 3 as your python. I
 am able to reproduce the problem if I do that.

 Let me see if I can either fix the build to work with python 3 or else
 convince the build to use python 2.
